Application December 18, 1945, Serial No. 535,725

2 Claims. 3

This invention relates to means for transferring coal and wood ashes from a furnace to a receptacle, by the use of a vacuum system, which is organized in the truck on which the final ash can or receptacle is mounted, and one of its objects is to provide a complete system for removing ashes by suction, including a receptacle or can which can be removed from the handling truck.

Another object of the invention is to provide means for securing the cover of the ash can or receptacle in place and additional means for allowing the air stream which is caused to flow into the can or receptacle to discharge to the atmosphere through a porous filtering bag.

With the above and other objects in view, the

invention comprises certain new and useful conhaving a suction intake 9 and an outlet or disa charge [0, the former being disposed in a horizontal relation to the truck and extending through the end wall I I of the truck and the latter being disposed in a vertical position and extending through the platform 5 of the truck.

In the fan casing 8 the rotary fan [2 is arranged upon the shaft I3 of an electrical motor, mounted to one side of the fan. A flexible suction conduit I4 is detachably connected with the suction intake, as by means of the bayonet joint l5, and the outer end of this flexible conduit or tubing is equipped with a large suction intake head It, which is shown to be of conical shape, and which is provided with a screen l l, to prevent heavy particles from entering the suction tube or conduit M.

The discharge N3 of the fan casing is connected to the base flange l8 of the vertical transfer conduit or pipe l9, which is provided on its upper end with an elbow i911, and a coupling flange 19b, disposed in a horizontal position.

The platform 5 supports the ash can or receptacle 20, and the cylindrical side wall 2| of this can or receptacle is provided with an intake 2 nipple 22, which may be coupled by the sleeve 23 to the flange l9b.

The can is provided with a bottom 24 of asbestos sheeting, suitably and permanently connected to the bottom 25 thereof. The can is also provided with one or more handles 26.

A dished cover 21 is slipped over the upper; end of the cylindrical wall 2|, and is normally held in closed position by means of the thumb screw 28, which is threaded on the arm 29 formed on the vertical rod 36, the lower end of which is secured by the rivets 3| to the truck. B unscrewing the screw 23 the cover may be raised, by means of its handle 32.

When not in use the flexible conduit or tubing may be supported on the metal arm 33, which is rigidly connected to the wall 2|, and this arm is equipped on its outer or forward end with a push and pull handle or knob 34, which may be utilized to propel the truck over the floor.

By disconnecting the upper end of the dis charge pipe [9 from the wall 2| of the can, and by releasing the hand screw 28 the can may be removed from the truck and inverted, after removing the cover, so that its contents may be discharged into the usual road truck.

With my invention all that is necessary to load the can with ashes, is to start the electrical driven fan by means of the switch 35, and then apply the conical intake I6 to the pile of ashes under the furnace. The suction produced by the action of the fan in the casing will draw the ashes through the flexible conduit and discharge them at considerable velocity into the vertical discharge pipe [9, by means of which the ashes will be conveyed or transferred to the can or receptacle.

The can top or cover '21 is equipped with an upstanding nipple 36, on which the air filtering bag 3'! is clamped by the ring or band 38. The air stream which is forced into the can by the action of the rotating fan will escape through the nipple 36 into and through the filtering air bag 31, while the dust and fine particles of the ashes will drop back into the can.

It will be seen, therefore, that the improved ash conveying device eliminates the formation of dust from the ashes in the furnace room, so that any woman or man may remove the ashes from a furnace without flooding the furnace room and the home or building With dust streams from the agitated ashes.

When the loaded can or receptacle is picked up by the public service employe and the cover again removed, the can will have been carried to the street, where it is dumped on the truck used for collecting the ashes of many homes and buildings.

Having described my invention, it is understood that various changes in the details of construction, their combination and arrangement, may be made, within the scope of the claims hereof.

I claim as new and patentable:

1. Anzash collecting means-comprising a truck and ground wheels for supporting the same, said truck having a platform, a fan casing supported on the truck below said platform and having a suction intake disposed horizontally and :a discharge outlet disposed vertically through the platform, an electrically driven :fan mounted to rotate in said casing to maintain a suctional pull through the intake, a receptacle mounted on the truck platform and provided with an asbestos bottom, a vertical transfer conduit on said truck platform spaced from .and extending parallel to said receptacle, said conduit having its lower end connected with the discharge 'outlet of the fan casing, means connecting the upper end of the transfer conduit to the receptacle, and a cover for the receptacle having an air outlet.

2. The construction set forth in claim 1, the truck having an upstanding rod connected at its lower end thereto, the upper end of the rod having an arm adapted to overlie the receptacle, and a hand screw threaded through the arm to engage the cover of the receptacle and lock the same in place against displacement from the air pressure generated in the receptacle.
